    Merlin VPN TAP Server - two clients

    Thanks so much. That was the issue. I was searching for TAP issues, not general VPN Server/client issues so I missed this thread. I had selected "Manage Client Specific options" in the Server advanced setting because of the "Allow client to client" communication. So now both clients connect...

    Merlin VPN TAP Server - two clients

    I have been running two ASUS Merlin routers with a permanent OpenVPN tunnel using TAP (one Server and one client) for 2+ years now. I know that TAP is not preferred, but I have some older equipment that wants to be on the same LAN segment so the routers are on the same subnet. It has worked...

    Need to Block DHCP from traveling across site-to-site TAP VPN Tunnel.

    Thanks, but I was hoping that I simply had to add a line to the "Custom Configuration" section of the VPN Client. I am using Merlin software for its richer VPN functionality, but I have only configured through the GUI. I don't even know where to begin to find the script area let alone...

    Bi-Directional VPN using two Asus Routers via OpenVPN NOT WORKING .. argh :(

    so, just uploading the firmware file and push "upload"? - how do i get back to stock firmware? Correct, and just upload the stock firmware if you want to switch back. Merlin looks like ASUS code, but with more features. (Maybe ASUS code looks like Merlin [emoji6]) so you are also saying i...

    Bi-Directional VPN using two Asus Routers via OpenVPN NOT WORKING .. argh :(

    I'll answer in order. The Merlin code installed as easily as a standard code upgrade. With TAP, yes both would have to be Net 81 or any subnet so long as they match. I chose to enable DHCP on each router with ranges .1 to .96 on one, and .200 to .254 on the other. (See last comment below.)...

    Bi-Directional VPN using two Asus Routers via OpenVPN NOT WORKING .. argh :(

    I am just reading your request for help. I have a working solution between my home and cottage. I can connect to devices on the client VPN router. It automatically reconnects to the VPN server (home router) should the connection ever get lost. To start with, you will need to install Merlin...

    Vpn probleem with Asus Rt-AC66U

    ISP routers are getting to complex to replace with a 3rd party box. My Asus is inside my home network and I really prefer having the extra firewalled layer anyway. As a result , my OVPN file simply has a 192.168.x.x WAN address that needs to be replaced with the ddns. Sent from my Pixel...

    Two thumbs up

    Two years ago I set up an Asus AC68U with an OpenVPN server for my wife's office of ten so they could remotely access resources when away from the office. As a result of Covid-19 they are all working from home and the Asus router is holding up to the beating. Way to go Asus and the OpenVPN...

    Tuning data usage - Help please

    I wanted to provide an update related to my original post. I upgraded to Merlin and this provided a number of extra features such as two VPN servers, multiple clients and more tools to display the state of things. Creating a router-to-router tunnel with TUN reduced chatter on the connection by...

    I have successfully connected multiple client devices to one Asus VPN server. I have connected one Asus router as a client and other client devices, but not two Asus router clients. That said, it should work. I trust you created two different login IDs on the VPN Server side and assigned one...

    I cannot find the "inbound firewall" parameter under the VPN section or the firewall section. anyone know how to configure it? I tried the LAN to LAN via an OpenVPN TUN connection and I did not have any success. I did not find a way to confirm that the routers has set up to routes to each...

    Tuning data usage - Help please

    That was the issue with my first attempt so I dedicated a separate router at home (AC66u) to accept the VPN connection specifically so there is no regular home LAN traffic going through it and leaking across the TAP link. Also, TUN did not allow me the 'reach' out, through the VPN server side...
